Well, I haven't taken a look for an existing gif or sprite file for it, but in Megaman 3 he gets the Top spin ability, which just makes him twirl around. Flipped upside, that could easily look like break dancing. Just food for thought.

Spark Man's music was my favourite out of all the old-gen MegaMan levels. Then again, I always whored that "plug in the 2nd controller and hold down Right on the D-pad for mega jump" cheat, so the song would stop playing when I 'died'... :(
